Milecastle 29
milecastle on Hadrian's Wall
Milecastle 29 (Tower Tye) was a milecastle of the Roman Hadrian's Wall. Its remains exist as a mutilated earth platform accentuated by deep robber-trenches around all sides, and are located beside the B6318 Military Road. Like Milecastles 9, 23, 25, and 51, a ditch has been identified around the Milecastle, and is still visible to a small extent. It has been postulated that this was as a result of the need for drainage on the site.
Construction
Milecastle 29 was a long-axis milecastle though the gateway type cannot be identified. Such milecastles were thought to have been constructed by the legio VI Victrix who were based in Eboracum (York), or by the legio XX Valeria Victrix who were based in Deva Victrix (Chester).
The milecastle was stated in 1840 as having dimensions of 63 feet (19 m) North-South by 58 feet (18 m) East-West with both southern corners (away from the wall) being rounded off.
The presence of a milecastle ditch is still evident, including a causeway crossing the ditch opposite the milecastle's south gate. A break in the north mound of the vallum and causeway over the vallum ditch (offset to the east) is also present. There is also disputable evidence of a causeway over the wall ditch opposite the milecastle's north gate.

Why this record matters
The phrase “milecastle on Hadrian's Wall” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 9, 2026. The linked authority identifier is Q15253380. Authority coordinates are 55.034, -2.175. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1840.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
